Optimal structural design is a methodology that optimizes the geometrical characteristics of a structure, for a given set of loads and limit conditions, so that the device meets a predetermined set of objectives. This wind turbine is mainly used in urban environments where wind conditions are different from those of non-urban wind turbines. The purpose of this work is to find the optimal structure that supports the aerodynamic device, with power of 1500 Watts, in order to reduce the applied stress as much as possible. The design and optimization of the wings will be carried out with software that supports topological optimization, such as ANSYS 2020. In this environment, the distribution of von Mises stresses before and after the removal of material from the original model will be studied. The output of the software was the basis for finding the optimal wing shape. The results of the present work can highlight the value of applying optimal design to a wide range of components and structures.
